Analysis of major intracellular solutes in R. leguminosarum bv. phaseoli 31c3 and R. etli 12a3. R. leguminosarum bv. phaseoli 31c3 (A) and R. etli 12a3 (B) cells were grown in M79-I medium containing 0.1 M NaCl and 20 mM mannitol, and cellular extracts were analyzed by 13C-NMR. Resonances due to trehalose (T), mannitol (M), and glutamate (G) are indicated. Peaks due to the carboxylate groups of glutamate (at 175.2 and 181.9 ppm) are not shown.
